The magnetic dipole moment of Earth is 8.00 ✕ 1022 J/T. Assume that this is produced by charges flowing in Earth's molten outer core. If the radius of their circular path is 2350 km, calculate the current they produce.

Therefore,

Current produce is

Explanation:

Given:

Magnetic dipole moment of Earth,

Radius = r = 2350 km = 2.35 × 10⁶ m

To Find:

Current, i =?

Solution:

Magnetic Dipole Moment:

A magnetic moment is a quantity that represents the magnetic strength and orientation of a magnet or any other object that produces a magnetic field.

Magnetic dipole moments have dimensions of current times area.

It is given by,

Where,

=  Magnetic dipole moments

i = Current

A = area =

Substituting the values we get

Therefore,

Current produce is

what is the question because that is not a question.
